Application, filed Febrnary 21. 1919. serialnp. 273,477.

' This invention plow-of the tractor type and one object of theinvention is to. provide a tractor plow and an improved method'ofmounting ,a

plow beam for vertical and transverse adjustment, the forward endportions of the plow beam being pivotally mounted andthe rear portionconnected with a rocker shaft whereby the plow carried by the beams maybe swung out of engagement with the ground when the rocker shaft isrotated. Another object of the invention is to so construct this plowmountingthat the plow .beams'may be set a proper distance apartaccording to the type of plows which are carried by the beams. 1

Another object of the invention 15 6 construct this plow that it will besimple to operate and very eiiicient in itsoperation.

This mventlon is illustrated n the accompanying drawlng wherem:

Figure 1 is a longitudinal sectional view of a plow. constructed inaccordance with my invention.

Fig. 2 is a the rear portion of the plow.

Fig. 3 is an enlarged detail of one of the adjustable plow hangers.

The main frame of the motor plowfor tractor is indicated in generalbythe numeral 3 and carriesbearing blocks .6 which rotatably support atransversely extending axle 7 on the ends of which are mounted theground wheels9 and upon which is also mounted the relatively largesocket wheel 10. A. relatively broad main drive wheel 9 is secured onthe other end of the. axle for propelling the tractor when the axle isrotated, this drive wheel being provided with suitable gripping elementsor cleats extending transverselyof the rim thereof at an in clination,as illustrated. A relatively large sprocket wheel 10 is mounted on theaxle for free rotation adjacent the inner end of the hub of wheel 9,this sprocket wheel being relates to an imp dl bearing fragmentarytopplan view of Specification of Letters Patent.

worm gear 28 is secured on the shaft 27 adjacent the upper end thereofand is in mesh with a worm 29 carried at the forward'e'nd of a steeringpost 30rotatablysupported in suitable standards 31' carried by the frameand provided with a steering wheel 32 at its rearward end positionedsoas to be readily accessible from the seat 14..

For plowing purposes, a hangersh aft a i *is rockably' mountedadjacentthe rearward end ofthe frame,,and at an inclination 1transversely thereof. in bearing blocks 35 carried by the beams 1 2 and8. Thisshaft is of substantial rectangularcross section I and isprovided with 'a plurality of hanger arms 36 adjustably'secured thereonby set screws. 37 or equivalent means. Thelower ends of thesearms areconnected by links I 38 tostandards 39'of plows 40 of suitable 1,

type. The forward ends 41 of the plowbeams are connected by clevises tothe stem portions 42 of T-shaped hangers 43 the heads 44 of which fitsnugly in a channelbeam 45 carried by the main frame adjacent theforward end thereof, thls beam beingincllned transversely of the framein parallelism with the shaft 34. The hanger 43 issecured in adjustmentin the beam by means of set screws 46 or in any other suitable manner,the'hangers 43 as well as the hanger arms 7 36, being readily adjustabletoward and away from each other to accommodate the required number ofplows thus permitting the use of one or two relatively large or heavyplows, or of several relatively light plows, as well as securing properand accurate adjustment of the plows. Also, when desired, the plows maybe replaced by suitable cultivating plows, the front arched axle '25being adapted to straddle rows of plants for cultivating purposes, thusreadily adapting the machine for'either plowing or cultivatingoperations. V

For raising and lowering the plows or other implements carried by theshaft 16, a hand lever 47 is secured to the shaft in position to bereadily accessible from seat 14.

This lever is. provided with a detent'which, coacts with a rack48carried by beam 3 to' secure 'the'lever in rocked adjustment. A

substantiallyiU-shapcd bracket 49 is secured on the upper face of beam 3and is provided with alined openings through its end arms which slidablyreceive a rod 50 adjacent the forward end of which is secured a collar51 against which abuts the forward end of an i P expansion coil spring52 mounted about the rod'and confinedbetween the collar and the rearwardend arm 53 of the bracket. The

rearward end of rod 50 is loosely secured to one end of a link 54 therearward end of which is pivoted to lever 47 above the pivotal axisthereof. The spring acts through its expansive force to assist inraising the plows,

thus permitting easy lifting of the same while providing a cushioningdevice to prevent the plows from being lowered too quickly andabruptlystopped.

It will be evident that there may be slight changes made in theconstruction and'arrangement of the details of my invention withoutdeparting from the field and scope of the same, and I intend to includevall such variations, as fall within the scope of the appended claim, inthis application in which a preferred form only of my invention isdisclosed.

What I claim is: r In a plow structure, a main supporting frame, ahanger shaft rockably supported thereby, means for operating said shaft,

hanger arms carried by the hanger shaft and adjustable longitudinallythereof for connecting said shaft to plows suspended beneath the frameia channel beam carried by the frame in advance of said hanger shaft, andhangers adjustable longitudinally of said beam and adapted to beconnected to the
